STT starts at M=6; how to approach?

[WJL]

If this belongs in Home Games, please forgive the mispost.

I've been playing in some home games with a difficult structure. Stacks are 10k, blinds are 400/200 with 100 ante on a 6-man STT. If memory serves, Harrington would multiply standard M by .6 to get an opening M=6 to start the STT.

Question is: Do I approach this game as a standard M=6 situation, since all the players are at the same level? I seem to either win these things or bust out very early, which is I guess what you would expect. This is a bunch of people who have been playing this structure together for a long time; there tends to be a lot of limping to see flops, and lots of call downs, but not much time to wait for a hand. Seems to me there is such a high luck factor in this structure that it would be difficult to be consistently successful, but some folks are. I could just play it for fun and forget about winning, but I'm just too danged competitive I guess.

Thanks for any thoughts you might have.
